COUNTERLINE APPLIANCE AND FASTENING ARRANGEMENT THEREFOR Filed March 19,1959 4 Sheets-Sheet 4 ATTORNEY Unite This invention relates to acounterline appliance and tates Patent mounting means therefor, and moreespecially to an v varrangement for fastening such an appliance in'position within an opening therefor in a countertop.

The present invention constitutes a continuation-in-part of ourcopending patent application, Serial No. 710,735, filed January 23,1958, now abandoned, in which one such appliance was disclosed. Incontrast therewith', this application considers the more general subjectof mounting and fastening a variety of counterline appliances in acountertop as, for example, a sink having either a single or doublebowl, the top burners comprising an electric or gas range or hot plate,a mixing bowl, and so on.

It is apparent from the exemplary appliances noted that the particularutilitarian aspects thereof have little significance with regard to theproblem of mounting and fastening the same in position along acountertop. However, with regard to the class of appliances consideredherein, each such appliance seats within an opening provided therefor inthe countertop, and may be characterized as being of generallysheet-like or planar form in that it has a perimetric rim or ilange thatrests upon the upper surface of the countertop. It should be noted thatin. this general classification, integral rim appliances (often referredto in the industry as self-rimmed, especially in connection with sinksWhere the term self-rimmed bow is also used) have posed heretofore adiicult mounting problem in that fixed fasteners or clamps are carriedthereby, and if one or more of such fasteners breaks olf, is stripped,or otherwise becomes ineffective, the entire appliance may be unusablefor the reason that the rim thereof cannot be drawn tightly against thecountertop at all locations to establish the necessary liquid-tight sealtherewith. In contrast thereto, this diiiiculty does not occur withseparate rim appliances, for the fasteners are carried by the separaterim which is readily replaced.

As a consequence, the usual practice has been to equip counterlineappliances with separate rims which are then fastened at the time ofinstallation both to the appliance and countertop; and to effect suchfastening, a great variety of clamping or mounting structures havebeenemployed. So far as is known, each of the clamping structures employedto secure separate rim appliances in position along a countertop ischaracterized by dividing the total clamping force developed between therim and counter and between the rim and appliance. Further, the manualact of mounting such separate rim appliances is difficult and cumbersomebecause it is usually necessary to effect a simultaneous clampingbetween the rim, counter and appliance. We are aware of the fact that anintegral rim counterline appliance and fastener therefor has beenproposed, but the concept of dividing the clamping force developed byeach of the lfasteners has been carried into Such integral rimappliances with the result that there is a tremendous loss in theeffectiveness of the `grip or` sealing engagement established betweenthe appliance rim and countertop. Additionally, in these integral rimstructures, the fasteners have been xedly located therealong asmentioned hereinbefore, whereby the appliance in its entirety must bereturned if one or more of the Xed fasteners becomes unusable.l

In accordance with the foregoing, an object of the present invention isto provide a counterline appliance and 3,040,338 Patented `lune 26, 1962fice establishing a liquid-tight seal with the countertop. An-

other object of the invention is in the provision of an integral rimappliance and fastening arrangement therefor, wherein the fasteners arequickly and easily interchanged when necessary, and wherein the numberof fasteners required for any installation may be determined on the job,whereby an effective liquid-tight seal can be established between thecountertop and appliance throughout the entire perimetric length of thelatter.

Still another object is that of providing in combination with anappliance having a generally planar marginal flange or edge portionadapted sealingly to engage the upper surface of a countertop, afastener arrangement including a mounting element carried by such flangealong the undersurface thereof and a plurality of fasteners adjustablycarried by the mounting element for selective positioning along thelength thereof to enable the fasteners to be utilized at the mostadvantageous locations to lnechanically anchor the appliance to thecountertop in sealing relation therewith. n

A further object of the invention is to provide fastener apparatus forsecuring the rim of an appliance to a countertop, in which the forceapplication developed by each of the fasteners is effectively utilizedand appears between the rim and countertop to clamp the rim thereto, andis not dissipated by needless application of a substantial portionthereof to thel rim. Still another object into with ease, and in which aclip or clamping element is engageable with a fastenerelement andundersurface of the countertop to clamp the rim to the countertop.

Yet a lfurther object is that of providing clamping apparatus of thetype described, in which the fastener element has an elongated shank,and in which the clip or clamping element engages the shank at twoaxially spaced locations therealong--one such location being along theplane of force transmission tothe countertop, and the other beingintermediate the rst location and the rim of the appliance. Additionalobjects and advantages of the invention will become apparent as thespecification develops.

`In the mounting of a counterline appliance in a countertop, thevcountertop is first provided with an enlarged opening therethrough ofsufficient size so as to accommodate readily the insertion thereinto ofany depending portions of the appliance. In the case of a sink, suchopening must be of suflicient size so as to accommodate the bowl orbowls of the sink; and in the case of an electric range, the openingmust be large enough to receive the deep well, understructure of theburner units and whatever ancillary equipment may be carried by therange. The appliance, whatever its functional utility may be, has asheet-like or generally planar perimetric flange or rim that is disposedin a generally horizontal plane and overlies the marginal edges of theopening in the countertop. Thus, in mounting an appliance, it is firstaligned with the opening in the countertop and is lowered theretowarduntil the depending portions of the appliance extend into the openingand the rim or perimetric flange engages the upper surface of thecountertop. Thereafter, `fastener structure is employed to anchor theappliance in such position and to draw portions `of the rim into tightengagement with the upper surface of the countertop. Preferably, theouter edge .portion of the rim is turned downwardly slightly so that ittends to bite into the countertop, and thus establishes a liquid-tightseal therewith which is of importance especially Iwhere the appliance isa sink.

Considering this arrangement in greater `detail in connection with thedrawings, it is seen that FIGURE 1 illustrates a counterline appliance Ain the Iform of an electric range or hot plate mounted in a countertopT. The rangeA may be of substantially conventional construction withrespect to the cooking or heating facilities provided thereby, and mayhave one or more burners and a ydeep well. In any event, a considerableamount of understructure is incorporated in such range, and thisunderstructure depends into the opening provided through the counter. InFIGURE 2. the appliance B takes the for-m of a mixer, and the centrallydisposed agitator provided thereby is positioned adjacent to the bottomwall of the container, which also depends into the opening providedtherefor in the counter T. In FIGURE 3, the appliance C is a single bowlsink, and the bowl thereof depends through the opening in the counter T.In FIGURE 4, the appliance D is a multiple bowl sink, and in thespecific with the numeral 18a.

- 4l illustration has two separate bowls that depend through the openingin the counter.

It Will be noted that in each instance, the counterline appliance has aperirnetric flange or rim that is horizontally disposed and overlies theupper surface of the countertop. Further, it is evident that thegeometric configuration of the appliance may take varied forms. Morespecifically, the mixer B shown inIFIGURE 2 has a generally cylindricalconfiguration, while the appliances A, C and D are generallyrectangular. Thus, the counterline appliance may be arcuate or circular,multiple-sided, etc.

Referring now to FIGURE 4 in particular, it is seen that the appliance Dis a sink having a pair of depending bowls 10. A sink of such type isgenerally formed of stainless steel; but with respect to the presentinvention, it may be made of any other suitable material. Surroundingthe bowlsltl is a perimetric flange or rim 11 that is horizontallydisposed and defines the upper surface of the sink. If the bowls 10 arenot centrally disposed, the flange 11 has a greater area along certainportions of the sink, as in the specific structure shown wherein theflange 11 has a greater width along one longitudinal edge of the bowls.When the appliance is mounted in a countertop, the perimetric flange orrim 11 overlies the marginal edge portion of the countertop that definesthe opening therethrough. In FIGURE 4, the counter is denoted with thenumeral 12, and it will lbe appreciated that the extent to which the rimoverlies the countertop is unimportant so long as the overlie issufficient to adequately support the appliance. Preferably, as shownbest in FIGURES 6 through 8, the flange or rim 11 is provided along theouter edge thereof with a downwardly turned portion 14 that tends togrip or dig into the surfacing 15 that covers the core 16 of thecountertop 12. As is well known, the surface covering 15 is generallyformed of a yieldable material, such as linoleum, plastic, rubber, etc.;and as a result, the engagement established between the downwardlyturned edge 14 of the rim and the surface covering 15 of the countertoptends to define a liquid-tight seal therebetween.

Extending along the undersurface of the rim 11 and flxedly securedthereto is a mounting element in the form of an elongated channel 18 ofinverted, generally U-shaped configuration, although the end portions ofthe channel legs are bent inwardly to define flanges 19 that generallyparallel the base of thechannel and consequently the rim 11. Themounting element 1S is formed of metal or correspondingly toughmaterial, for the forces developed between the rim 11 and countertop 12are applied to the rim through the mounting element. The mountingelement may be spot welded or otherwise secured to the rim 11, but ispreferably affixed thereto by an adhesive (as shown in FIGURE 13). Theadhesive may be one of the commercially available synthetics such as athermosetting synthetic resin, one of the epoxies for example, or athermoplastic resin such as one of the rubber base types. If anepoxyresin is used, ordinarily it Will -be cured under heat and pressurealthough various formulations are available which afford considerablelatitude in temperature selection. When force is applied across the rimand mounting element during curing of the adhesive, portions of theadhesive will be squeezed from Ibetween the mounting element and the rimand will form beads, as shown in FIGURE 13 and which are denoted In thisfigure, the size of the beads 18a is exaggerated to make theillustration clear.

It is clear from FIGURES 6 through 8 that the mounting element 18 isdisposed entirely beneath the flange or rim of the appliance, and isspaced inwardly from the outer perimetric edge of such flange so that itcan depend freely into the opening in the countertop. Also, the mountingelement in the specific forms shown herein, substantially parallels theouter edge of the rim, and is interrupted at least at one pointtherealong so that fastenersl can -be inserted thereinto and removedtherefrom, as will be described morefully hereinafter. The mountingelement 18 carried by the appliance D, as shown best in FIGURE 4,comprises four separate sections or segments, one for each of the fouredge portions of the appliance. Thus, a plurality of interruption isdefined by the composite mounting element, and such interruptions appearrespectively at the four corner portions of the appliance. However, ifreference is made to FIGURE l, it will be seenthat the mounting element18 carried by the appliance A is formed in two sections; and thus,interruptions appear only at two of the opposite corner portions of theappliance. In FIGURE 2, the appliance B is of generally cylindricalconfiguration, as is the rim 11" thereof, and therefore the mountingelement 18" has a circular configuration and is provided with but oneinterruption throughout the entire length thereof. Similarly, themounting element 18"' carried by the appliance C shown in FIGURE 3 hasonly a single interruption throughout the entire length thereof, andsuch interruption appears adjacent to one corner portion of the rim orperimetric flange 11 of the appliance.

Returning again to FIGURES 6 through 8, it is seen' that the mountingelement 18 carries one or more fasteners 20, and the precise number offasteners employed will depend upon the nature of the particularappliance being mounted in the countertop and the size, or morepointedly the perimetric length, of the appliance. FIGURES 1 through 4make it clear that a plurality of fasteners is used with each of theappliances illustrated. Each of the fasteners is longitudinally movablealong the length of the mounting element, and may be inserted thereintoor removed therefrom at ony one of the interruptions along the mountingelement. As a result, fasteners may be added in the numbers necessaryafter the appliance is supported on the countertop; and further, eachofthe fasteners may be moved to a location which is most strategic inthe clamping of the appliance to the countertop.

In the exemplary fastener illustrated, it takes the form of an elongatedbolt having a head 21 that is slidably received Within the channel ormounting element 18,' and having also a threaded shank that depends fromthe head Z1 in a direction substantially normal to the plane of the ange11. In this form of the fastener, the head 21 is square-shaped and isdimensioned so that it is slidably receivable within the channel 18.However, the interior dimensions of the channel and the width of thehead Z1 are so related that the fastener cannot rotate with respect tothe channel.

Cooperatively associated with each fastener is a clip or clampingelement 22 adapted to be drawn upwardly along the -shank of the fastener20 and toward the mounting element 18 so as to engage a portion of theclamping element with the undersurface of the counter, and thereby toeffect a clamping force between the flange 11 and the countertop. Theclamping element 22 has a somewhat J-shaped configuration, and a baseleg portion Z4 thereof extends axially along the fastener and adjacentto its upper end engages the shank of the fastener. In specific terms,the base 24 is turned laterally at its upper end to define a relativelyshort, gen erally horizontal upper leg 2S provided with an aperture 25atherethrough that receives the shank of the fastener 20 therein. At itslower end, the base 24 is also turned laterally to define an outwardlyextending, generally horizontal lower leg 26 that extends under thecountertop 12 and is adapted to engage the same. Preferably, the outerend portion of the elongated lower leg 26 is turned upwardly, as shownat 28, to form a relatively sharp edge adapted to dig into theundersurface of the countertop which, as shown in the drawings, isgenerally of wooden construction. The lower leg 26 has an'aperture 26atherethrough that is aligned with the aperture 25a, and is also adaptedto receive the shank of the fastener 20 therein. Both of the aperturesin the clamping element 22 have a slightly greater diameter than that ofthe shank of the fastener 20 so that initially the clamping element isfreely movable axially along the fastener.

Means are provided to urge the clamping element 22 upwardly along thefastener 20 and toward the mounting element 1S so as to engage theelongated leg 26 of the clamping element with the undersurface of thecountertop. In FIGURES 4 through 6, such means comprises a nut 36 thatthreadedly engages the shank of the fastener. FIGURH- 7 and 8 show therelative positions of the perimetric -ange 11, countertop 12, fastener20 and yclamping element 22. as the nut 30 is tightened against thelower elongated leg of the clamping element to effect the `clampingaction between the flange and the upper surface of the countertop.

A modified fastener structure is illustrated in FIG- URES lO through 12,inclusive; and since the only structural variation is found in thefastener and clamping element, the same numerals as those usedheretofore to identify the perimetric fiange, countertop, and mountingelement are again employed. However, with respect to the fastener andclamping element, the numbers correspondingto those used hereinbeforeare primed to indicate structural variation. In this form, the fastener20 comprises an elongated bolt having a head 2.1 that is generallycylindrical so as to permit rotation thereof within the channel ormounting element 18. Depending from the head 2l is a threaded shank thatterminates at its lower end in a slot 31 adapted to receive the blade ofaV screwdriver therein. While a nut might be employed as with thefastener 20y and clamping element 22 to tighten the clamping element,lWe prefer to thread the aperture 26a in the elongated lower leg '25 ofthe clamping element Z2. so that it can threadedly engage the shank ofthe fastener 20. Thus, to draw the clamping element 22 upwardly towardthe countertop and mounting element, the fastener 20 is rotated by meansof a screwdriver or similar instrument having a blade which can beinserted into the slot 3l; and because of the threaded character of theaperture 26a, the clamping element 22 moves upwardly along the fastenerwhen 'the fastener is turned or rotated in the appropriate direction.Otherwise, the structure and its function is the same as that heretoforedescribed, and it is evident that the head Ztl of the fastener will bedimensioned so that it is freely slidable longitudinally along thechannel or mounting element 18.

vA further modified fastening arrangement is illustrated in FIGURE 13,and it varies from those heretofore described only in that it embodiesthe principles of the rapid or quick fastener which is sometimesreferred to as the Tinnerman fastener. Thus, the fastener 20" has acylindrical head 2l which permits the fastener to be rotated in thechannel 18, and the lower end of the fastener is slotted so as toreceive a screwdriver blade. The fastener `22 may be constructed exactlylike the fastener 22, but the nut 30" is slotted and tongued so that itcan be pushed upwardly along the shank of the fastener 26 withoutrotating one with respect to the other. Of course, final tightening maybe accomplished by rotating the fastener 20 if this should be re-vquired. It may be noted that the lower elongated leg 26 of the clampingelement could be slotted and tongued so as to/define a quick-typefastener such as that provided by the element 30", thereby eliminatingthe need for the element 30".

The invention heretofore described may also be used in slightly variedenvironments to effect broadly the clamping of one element to another.FIGURES 14 through 17, inclusive, show arrangements exemplary of suchuses. For example, it is ordinarily customary to provide a wiring box inassociation with an electric range or hot plate so as to facilitate theconnection of the various heating elements with the incoming power line,and to fuse each of the heating elements where this spaanse may beeither required or desirable. In this particular connection, a problemhas always existed of establishing a satisfactory ground connectionbetween the appliance per se or the exposed metal surfaces thereof andthe incoming ground line. Such a ground connection is necessary for,without explanation, it will be apparent that if the exposed metalsurfaces of the appliance are not grounded, a serious hazard ispresented to those persons using the appliance.

FIGURE 14 illustrates a wiring box secured to the undersurface of theappliance A of FIGURE l, and the 'oox is in engagement withsucnundersurface to establish both a mechanical and electricalconnection therewith. The box is denoted with the numeral 32, and isequipped along the upper surface thereof with a plurality of projectionsor protuberances 33 that actually engage the undersurface of theappliance and space the top wall of the wiring box therefrom. Thislarrangement permits a cover 3d to be readily removed from the wiringbox and to be replaced thereon, and affords access to the interiorthereof. The box 32 is held in engagement with the appliance by means ofthe fastener 20 heretofore described which is slidably carried by thechannel or mounting element 18' and by a clamping element 22". Thefastener, clamping element and nut 30 are similar to the embodimentheretofore described in connection with FIGURE 13, and the onlyvariation is that the bottom leg 26 of the clamping element is somewhatlonger. Thus, the same channel 18' used in securing the appliance to thecountertop T is also employed in mounting the wiring box 32, andprecisely the same fastener and clamping element may 'also be used but,as illustrated, it may be advantageous in some installations to elongateslightly the lower leg of the clamping element. FIGURE 15 showsschematically the circuit connections provided by the box 32, and itenables the various conductors 35 through 38 leading to the individualheating elements to be connected by suitable fusing to the incoming line39. It should be noted that the ground line is connected directly to thewiring box 32, and consequently the rim of the appliance is also thenelectrically connected through the box and protuberances 33 thereof tothe ground line.

FIGURES 16 `and 17 illustrate a slight variation in that the wiring box32 is secured directly to the mounting element or channel 18', andtherefore the protuberances 33 may be omitted since the channel spacesthe box from the undersurface of the appliance and thus permits removaland replacement of the box cover 34. This configuration is most suitablewhere the channel 18 is welded to the perimetric flange -ll of theappliance for then the appliance is electrically connected to the boxthrough the channel. In this construction, it is preferable to employ apair of fasteners and clamping elements which, as shown in FIGURE 17,are oriented along the axis of the channel i8. Any of the fasteners andclamping elements heretofore described may be employed; but in thespecific illustration, the fastener 20, clamping element 22 and nut 30are used.

In all forms of the invention set forth above, one component iseffectively and positively clamped to another; and in particular,counterline appliances of various types are clamped in position along acountertop so as iixedly to relate the appliance thereto and at the sametime to establish a liquid-tight seal between the rim or perimetric angeof the appliance and the countertop. It should be mentioned that inactual installation, the workman may place a layer of plumbers adhesivebetween the upper surface of the countertop and the downwardly turnededge portion of the perimetric liange to supplement the desired sealingrelationship. Great flexibility is afforded the workman in installingthe appliance for he can determine on the job the number of clampingstructures required to compensate for warpage or other irregularities inthe countertop and to supplement the anchorage of the appliance to thecountertop at areas of particular stress.

Moreover, there is never a need to discard an appliance or return thesame, for the danger of an appliance being unusable because ofinsufcient or inoperative fasteners is obviated,

Not only are the fasteners selectively positionable along the mountingelement or various segments thereof, but the clamping force developed ineach unit is transferred to the rim of the appliance only through thefastener-and mounting element. Consequently, a division of the developedforce or dissipation thereof does not appear in this construction; butrather, such forceis effectively utilized. Each clamping element engagesthe shank of ya fastener therefor at two axially spaced locationstherealong-one being along the line of force transmission to theundersurface of the countertop (that is to say, along the plane dened bythe lower elongated leg 26 of the clamping element), and the otherintermediate this plane and the rim of the appliance. This arrangementreinforces and strengthens the clamping element, and preventsdeformation thereof without using heavy expensive metal for the clampingelement.

It will be noted that in all embodiments of the invention, forceapplication to the flange or rim of the appliance is imparted theretothrough the mounting member or channel extending along the undersurfacethereof, except for the force developed between the rim and underlyingmarginal edge portion of the countertop. Thus, neither the fastener norclamping element bear directly against the underside of the flange, anddistortion o'r other damage to the ilange which frequently accompaniessuch an undesirable force application is obviated. This particularconcept is illustrated perhaps most clearly in FIGURE 13, wherein theclamping element 22" bears directly against the channel 18. Properselection of the gauge and/ or treatment of the clamping element enablesthe bottom, laterally extending leg thereof to have a yield point suchthat it will give when a force in excess of a predetermined magnitude isapplied thereto, and such predetermined force will be less than theforce that will cause deformation of the appliance rim upon tighteningof the fastener and clamping element.

While in the foregoing specification embodiments of the invention havebeen set forth in considerable detail for purposes of making an adequatedisclosure thereof, it will be apparent to those skilled in the art thatnumerous changes may be made in those details without departing from theprinciples and spirit of the invention.
